General Optics
Protective Windows
Protect valuable scan lenses and focusing optics in industrial laser systems from debris, backspatter, and other workplace hazards with these plane parallel windows.
Coherent offers protective windows in both ZnSe and Ge. These can be integrated directly into a scan lens or focusing assembly or provided separately.
Protective Windows Selection
Choose ZnSe windows with our standard antireflection coating, or Ge optics with a diamond-like carbon coating (DLC) which will withstand the most severe conditions.
